%X 雅砻江发源于青海省巴颜喀拉山南麓，流域横跨中国地形一、二阶梯边界，地质地貌形态丰富。雅砻江流域巨大的地形反差与区域的构造背景密切相关。雅砻江流域位于西南季风和高原季风的交汇地带，季风带来大量的降水，地表侵蚀作用强烈，水系较为发育；加之快速隆升的构造背景，该区河流强烈下切，下切幅度可达3000 m以上，形成宏伟、壮观的高山峡谷地貌。河流阶地是一种典型的层状地貌，其在研究新构造运动、古气候变化、古水系演化以及侵蚀基准面变化等方面具有不可替代的优势。在雅砻江河谷发育了较为完整的河流阶地序列，阶地保存相对完整，是研究河流阶地与构造运动和气候变化关系的极佳场所。<br />
Originating from the southern foot of the Bayankala Mountains in Qinghai Province, the Yalong River basin spans the boundary of the first and second echelons of China’s topography and is rich in geological and geomorphologic forms. The great topographic contrast in the Yalong River Basin is closely related to the tectonic background of the region. The Yalong River basin is located at the intersection of the southwest monsoon and the plateau monsoon. The monsoon brings a lot of precipitation, the surface erosion is intense, and the water system is relatively developed. Coupled with the tectonic background of rapid uplift, the river in this area is strongly cut down, and the cut amplitude can reach more than 3000 m, forming a magnificent and spectacular mountain canyon landform. River terrace is a typical stratified landform, which has irreplaceable advantages in the study of neotectonic movement, paleoclimate change, paleo-water system evolution and erosion base level change. The Yalong River Valley has developed a relatively complete series of river terraces, and the terraces are relatively well preserved, which is an excellent place to study the relationship between river terraces and tectonic movement and climate change.
